I think valgrind experienced a division by zero.

If you can re-build valgrind, then a quick-and-dirty work-around
might be
> Word adv = (op_code / (info.li_line_range ?: 1))

where "x ?: y" is a deprecated-but-useful slang for "x ? x : y".
Also, one probable reason for the bug reporting system rejecting
your first submission is the many consecutive lines that begin with
"00:08.54 GECKO(319869) ". The work-around for this is to put
the text of the valgrind complaint into an attachment, and say
"See the attachment for the full text of the valgrind complaint."
Thank you for the comment.
I will try to re-submit the bugzilla entry.
I didn't realize the lines starting with timestamp string such as
""00:08.54 GECKO(319869) " causing the problem.
I thought there were no URLs, and so no spam. :-)
Sorry, somehow I overlooked your e-mail and thus this very tardy response.
TIA
